您可以简单地使用CATransaction:

self.imageView.hidden = NO;

[CATransaction begin];

[CATransaction setCompletionBlock:^{

    self.imageView.hidden = YES;

}];

self.imageView.animationDuration = 2;
self.imageView.animationRepeatCount = 2;
self.imageView.animationImages = [[NSArray alloc]initWithObjects:
                                  [UIImage imageNamed:@"cat_blink0000.png"],
                                  [UIImage imageNamed:@"cat_blink0001.png"],
                                  [UIImage imageNamed:@"cat_blink0002.png"],
                                  nil];

[self.imageView startAnimating];

[CATransaction commit];

CATransaction 将动态等待动画完成...
